Application filed November .16, 1910. Serial No. 592,688.

To all whom it may concern:

Be it known that I, JULIUS CAESAR BRAD- SHAW, a citizen of the UnitedStates, residing at Little Rock, in the county of Pulaski and State ofArkansas, have invented certain new and useful Improvements inRailwayGrossings, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to certain new and useful improvements in railwaycrossings and has for its object to provide a very'novel arrangement ofthe tracks and switches .w'hereby cars running in any direction may bequickly switched from one track to another to change the direction ofmovement, without loss of time or blocking the system. The invention hasfor a. further object the provision of a twenty track terminal orcrossing switch system whereby cars running in any direction may beswitched in a number of different ways to turn the car for movement in areverse direction or for movement upon an intersecting track, thusavoiding the possibility of collision and also eliminating delay in therunning of the cars which is frequently caused by the necessity forswitching the cars at .the intersecting points of the tracks.

Vith the above and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully de scribed and claimed, and illustrated in theaccompanying drawing which represents a railway crossing, the tracks ofwhich are arranged in accordance with the present invention.

In the drawing parallel intersecting main tracks are shown. These tracksare respectively designatedN, S, E and W to indicate the direction ofmovement of the cars. In each of the tracks two sets of doublepointedswitches 5 and 6, respectively, are arranged. These switches controlthemovement of the cars over the tracks which connect the main tracksrunning in opposite directions, or, in other words, which connect thenorth and south tracks with the east and west tracks, .two sets of suchswitches being employed and extending in opposite directions from eachof the main tracks.

As a practical illustration of the operation of the invention, assumingthat there are two cars upon the east bound track, one

of which is a through car and the other of which is to be switched uponthe west bound track on its return trip, the switch 6 is opened andthefirst car moves over the track 7 upon the south bound track andcontinues in this direction. The second car, after the first car haspassed beyond the switches 5 and 6, is moved over the track 8 by closingthe inner switch 5. This car, therefore, moves upon the north boundtrack beyond the switch point 6 arranged therein. The switch 6 in thenorth bound track being closed, the car moves over the same and theswitch 5 in said track is opened so that the car moves over the track9'and upon the rails of the west bound track. Thus the car is reversedand continues upon its return trip. This operation applies to a carmoving in any direction. For instance a car on the north bound track maybe reversed by opening the switch 5 to direct the car upon the track 9from whence it moves on thewest bound track beyond the switch 6. It thenreturns over tracks 10 after the switch 6 is opened and is directed uponthe south bound track and continues its return trip. Similarly, a carrunning upon the west bound track may be reversed by opening the switch6 to direct the car upon the north bound track and upon reversing themovement of the car and opening the switch 6 in the north bound track,the car may be returned upon the east bound track, as will be readilyseen from reference to the drawing.

From the above it will be observed that there are two tracks connectingeach of the main intersecting tracks with each other, the tracks 7, S 9and 10 connecting the north and south tracks with the east and westtracks upon one side of the crossing, and similarly arranged'tracks 7,8, 9, and 10 also connecting the north and south tracks with the' eastand west tracks upon the opposite side of the crossing. There are twosets of the tracks 7 8, 9 and 10 and also of the tracks 7', 8, 9' and10, said tracks extending in opposite directions and connecting each ofthe north and south and the east and west main tracks with each other.It will thus be seen that a car may be switched from any one of the mainintersecting tracks onto either of the other maintracks running at rightangles thereto, thus avoiding delay in the movement of the cars over thecrossing and also permitting of the switching of two or more cars at onetime.

o The switches may be of any preferred construction and the tracks attheir intersecting points are connected and braced by means of thecastings 12 in the usual manner.

The above described arrangement of the switching tracks calls for atotal of twenty tracks at the intersection of the main tracks of thesystem. The tracks may be properly arranged and installed at butslightly greater cost than the present system of railway trackconstruction and permits of the handling of a large number of cars in avery expeditious manner, thus avoidin blocking or congestion of thesystem and of street traflic.

While I have particularly shown and described the preferred constructionand arswitch rails connecting each of the switches in each of saidintersecting tracks with one of the switches in-each of the tracksextending at right angles to the same.

2. A railway crossing comprising parallel intersecting. main tracks, adouble set of switches located in the main tracks on each side of theirintersecting points and Switch ing rails connecting one of the switchesin each of the main tracks with one of the switches in the intersectingmain track'upon each side of the intersecting point of said main tracks.I v 3. A railway crossing comprising a plu rality of intersecting maintracks, a double set of switches located in each of the main tracks uponeach side of the intersecting point of said tracks, and switch rails connecting each of said switches in the same main track with one of theswitches in each of the main tracks running at right angles to the firstnamed tracks, and upon each side of the intersecting'point of saidtracks.

In testimony whereof I hereunto ailix my signature in the presence oftwo witnesses.

JULIUS CAESAR BRADSHAW.
